Abstract (en)
[origin: EP0447918A1] The invention relates to a tolerance deviation compensation device for arrangement in a coupling (10) consisting of at least two coupling parts (12, 14) between a drive- and gripper-side part of a robot arm, the coupling parts being movable relative to one another. The tolerance deviation compensation device permits large deflections with a very high degree of restoring accuracy by providing a bearing and guiding device for defining the movement of the coupling parts relative to one another, by providing a pretensioning device (46, 48) for limiting the deflection movement of the coupling parts relative to one another and for pretensioning into an undeflected neutral position, and by the fact that the pretensioning device has an engagement element (58, 60) which is arranged on one coupling part and engages between two spring elements (46, 48) arranged on the other coupling part, the spring elements pretensioning the engagement element towards a neutral stop arranged on the other coupling part. <IMAGE>
